This is extremely difficult to answer. Most of my favourites are dead, because I love the era of classic Hollywood and most people of that era are gone. Favouirite and best aren't the same term. hmmm. Of the classic era, I love Jack Benny and Sid Ceasar the most. Of the era after that, George Carlin and Richord Prior. Of those who are alive, Join Stewart. I couldn't pick just one among the dead. But alive was easy to answer.
